Hi Nikki --
I was also curious about the consent factor, as Liz suggested. A good site
to check that may have such a tool in place is http://oneforty.com and feel
free to tweet Laura Fitton at @pistachio if you can't find something (or to
see if it exists).
Related, depending how you "scrape" the content through the API, there have
been cases when Twitter management has suspended accounts for suspicious
activity.
